AI is transforming content generation, consumer dynamics, personalization, and adapting to market shifts. While these features can aid in speeding up the decision-making process and provide more targeted marketing, they also cannot be solely evaluated in terms of efficiency. Current studies tend to focus on either technology performance, consumer involvement or ethics, with less insight into their actual connection. This paper aims to fill this gap by summarizing current knowledge about AI-assisted marketing, personalization, consumer trust, ethical governance, and brand engagement. Based on this review, it constructs an integrated model to explain how the capabilities of AI act as influences on consumer responses, and how the same application can have varying outcomes across market and social contexts. This paper recognizes three tensions: disclosure and trust, personalization and privacy, and efficiency and authenticity. It also outlines eight posited relationships among factors of perceived authenticity, relevance, emotional connection, cultural sensitivity, human oversight, and consumer engagement that are subject to testing. This paper suggests that as AI empowers consumer–brand communication and enhances human decision-making, it is capable of generating enduring marketing value rather than performing mere communication automation. For practitioners, this demands transparency, ethical data application, quality human supervision, responsive to culturally relevant communication, and synaptic engagement beyond digital metrics and numbers. Overall, the review highlights that achieving the success of AI application within the realm of marketing is dependent on the balance of technological ability, ethical obligation and accountability. As a result, AI can enhance customer satisfaction and loyalty. The very same technology can fail to strengthen the relationships that brands are looking to establish if neglected.

This study examined the effect of fiscal deficits on private savings in Nigeria from 1981 to 2023. The research used data on private sector savings deposit, fiscal deficit as a percentage of gross domestic product - GDP, broad money supply as a ratio of GDP in %, private sector credit as a ratio of GDP in % and exchange rate from the statistical reports of Nigeria’s central bank. The main analytical technique applied was the Autoregressive Distributed Lag - ARDL Bounds testing method. The results revealed there is a long-term connection between the variables studied. The results also revealed that in the long run, fiscal deficit and private sector credit as a ratio of GDP in % have a positive though not significant relationship with private savings. At the same time, broad money supply as a ratio of GDP in % has a negative association with private savings. Meanwhile, exchange rate has a positive and significant relationship with private savings. In the short run, fiscal deficits, private sector credit as a ratio of GDP in %, broad money supply as a ratio of GDP in % and exchange rate have positive association with private savings. Interestingly, only broad money supply as a ratio of GDP in % is statistically significant. Based on these findings, the study submitted that sustained increases in private savings require policies that enhance household income, strengthen financial intermediation, ensure macroeconomic stability, and improve the productivity of government expenditures. Such measures are more likely to generate meaningful and lasting improvements in the nation's savings performance and economic development. Policymakers should encourage deposit money banks and other financial institutions to extend credit to sectors with high growth and employment potential, including agriculture, manufacturing, small and medium-scale enterprises (SMEs), and technology-based industries. Such measures would enhance productive capacity, increase income generation, and subsequently boost private savings. Policymakers should prioritize measures that enhance income levels, strengthen financial sector development, improve financial inclusion, and maintain macroeconomic stability. These policies are more likely to generate sustainable increases in private savings and support long-term economic growth and development in Nigeria.
